The endoplasmic reticulum (ER) plays a pivotal role in the regulation of cytosolic Ca(2+) concentrations ([Ca(2+)](cyt)) and hence in insulin secretion from pancreatic beta-cells. However, the molecular mechanisms involved in both the uptake and release of Ca(2+) from the ER

We examined cytosolic concentration of Ca2+ ([Ca2+]i) in canine airway smooth muscle using fura 2 fluorimetry (global changes in [Ca2+]i), membrane currents (subsarcolemmal [Ca2+]i), and contractions (deep cytosolic [Ca2+]i). Acetylcholine (10(-4) M) elicited fluorimetric, electrophysiological, and mechanical responses. Caffeine (5

In this study we evaluated the in vitro effects of 4-chloro-3-ethylphenol (CEP) using cumulative (12.5-200 micromol/L) or bolus (75 and 100 micromol/L) administrations, on muscle specimens from malignant hyperthermia (MH) susceptible and MH nonsusceptible patients, respectively. In the cumulative CEP
In single mouse skeletal muscle fibers injected with fluorescent Ca2+ indicator Indo-1, 4-chloro-m-cresol (chlorocresol, 4-CmC) and its lipophilic analogue 4-chloro-3-ethylphenol (4-CEP) increased resting myoplasmic free [Ca2+] ([Ca2+]i) in a dose-dependent manner. In this regard, 4-CEP was more potent than 4-CmC

To study the spatial and temporal distribution of intracellular Ca2+ concentration in cultured bovine pulmonary artery endothelial (BPAE) cells. Cultured BPAE cells were loaded with Fura-2 and observed under an inverted microscope coupled to a microfluorimeter, which enables pixel-to-pixel ratio
